Application filed March 12, 1903. Serial No. 147,505.

T all 7.071.071?, it may concern:

Be it known that I, ANDERS CARLSON ScHUL'rZ, acitizen of the UnitedStates, residing at Camden, in the county of Camden and State of NewJersey, have invented new and useful Improvements in Journal-Bearings,of which the following is a specification.

This invention relates to journal-bearings; and the object thereof is toprovide an adjustable bearing which will reduce the friction caused bythe rotation of a' shaft to a minimum.

Another object is to prov-ide an effective form of adjustment tocompensate for Wear caused by the continuous rotation of a shaft,

- so that a iirm and even bearing will at all times be provided.

Other objects, as well as the novel details of construction, will beapparent as the nature of the invention is better understood, and thesewill become obvious by reference to the following description, togetherwith the accompanying drawings, in which- Figure 1 isa perspective viewof the' preferred form of bearing 0r journal-box, showing a portion of ashaft projecting therefrom. Eig. 2 is a vertical cross-sectional viewthrough the bearing, showing the casing or clamping device for theadjustable sections in elevation. Eig. 3 is adetail perspective view ofthe top of the upper' half of the journal-bearing. Fig. 4 is a verticallongitudinal sectional view through the box, the axle or shaft beingshown in elevation. Eig. 5 is an end View of a slightly-modified form ofbox, and Fig. 6 is a similar View of a still further modified form.

The box which embraces the axle or shaft is a sectional one and caninclude two or more sections, properly held together by a suitable bandor casing. In the preferred form shown in Figs. 1, 2, 3,and 4:) I haveillustrated the box as consisting of upper and lower vertical sections,designated by the reference-numerals 1 and 2 and slidable with relationto each other. Each section comprises a block approximately rectangularand provided at one side with a semicircular groove 3. The arc of this"groove is somewhat greater than the arc on which the circumference ofthe shaft 4 is struck, so that aspace will intervene between the outersurface of the shaft and the inner wall of the groove. Within the spacethus formed are arranged a plurality of antifrictionrollers 5. The twogrooves in the respective sections are arranged so that when the twosections are brought together, as shown in Figs. 1, 2, and 4,acircular'seat will be formed for the reception of the shaft, and anywear upon the grooves can be readily taken up by adjusting devices to bereferred to hereinafter. By reference to Fig. 3 it will be noticed thaton the opposite edges of each block are ribs 6, having extending ends 7,parallel with' each other and spaced apart at proper intervals to formgrooves 8 for the reception of similar coinciding ribs on the oppositemember. The grooves and ribs are of approximately the same Width anddepth, so that the ribs on one member will interlock with the grooves inthe other. In order that this may readily be accomplished, the ribs onthe member 1 are alternately arranged with relation to those on themember Q, so that the ribs on each member aline with the grooves, on theopposite member. As the grooves and ribs are vertically disposed, thetwo members will be verticallyadjustable with relation to each other andare held in engagement by means of a sectional casing or clamping devicecomprising the upper and lower members 9 and 10, which pass over the topand bottom and embrace tlie sides of the' respective box-sections.Cppositely-disposed flanges 11 and 12 areprovided for the top member ofthe clamping device,.and these flanges are parallel with the iianges 13and 14 on t'he bottom member..

The two flanges can be secured together by means of suitable bolts orfastening devices 15, which pass therethrough for this purpose. It willbe observed that the horizontal plate at the top of the clamping deviceis spaced apart from the top edge of the upper member 1 of the sectionalbox. This is to permit a vertical play of the upper member of thesectional box to provide for wear and permit an easy adjustment tocompensate therefor. The adjustment can be accomplished and the weartaken up by the adjusting-screws 15, projecting through the top plateand bearing IOO upon the member 1 of the sectional box. Thus by turningthe adjusting-screws 15 to slide the upper member upon theopposite one airm even bearing will be provided for the shaft or axle 4. The peculiarmanner of arranging the upper and lower interlocking members will permitof a perfect pressure being exerted upon the rollers 5, and while thisform is particularly designed as a general box for car-axle it isobvious that it will be equally applicable for line-shafts and similarjournals.

In Fig. 5 a slightly-moditied form of bearing is provided, whichconsists of a plurality of quadrantal sections, each section beingapproximately pyramidal in form. These sections are each designated bythe referencenumeral 16, and the diverging edges are provided or formedwith longitudinally-disposed interlocking ribs 17, similar to the ribs 6on the sections shown in Figs. 1 to 4, the ribs on one sectionalternating with those on the other, so that when the four quadrantsare' in interlocked position an approximately rectangular bearing willbe provided with a concentric opening through which the shaft projects.Suitable antit'rictional rollers 5a are arranged in the central opening'18, formed by the inner ends of the several sections, and these rollersare arranged in circular series around the shaft. In order that theseveral sections will be held in proper interlocked relation, I providea casing similar to the one illustrated in the form shown in Figs. 1 to4 and which comprises an upper and lower approximately U-shaped memberthe meeting ends of which are formed with outwardly-projecting paral-'lel anges 121 and 13u. f In this form the wear on the bearing is takenup by the adjustingscrews 15*L in the top of the casing and thetransverse horizontally projecting bolts or screws 15b, extendingthrough the sides of the casing and bearing against one of the sidequadrants. In view of the fact that the meeting edges of the severalquadrants are diagonally disposed the pressure exerted by the screws 15and those designated by the reference-numeral 15b will cause thesections to become rigidly interlocked.

In the form shown in Fig. 6 the shaft is surrounded by a plurality ot'sectors or members 19, forming a central opening for the reception ofthe shaft and designed to receive the antifriction-rollers 5", which areinterposed between the shaft and the edge or' the the edge of eachmember is provided with in-` terlocking ribs 2O for engagement with cordresponding grooves in the adjacent section. The bearing thus provided bythe several sections is approximately triangular in form, and thesectors are held together by acasingcomprising upper and lower sections21 and 22, the meeting ends of which are formed with parallel flanges12c and 13. Suitable fastening devices, such as bolts or rivets 23, willbe used to secure the flanges to each other, and thereby hold the casingin proper position to lock the sectors together. 15C and 151 designatetwo sets of clamping-screws, which are carried bythe upper section andare designed to be turned so as to force the sectors in rigidintel-locked relation.

It will be observed that the same general plan is followed in all ot'the forms and that the variations consist, chiefly, in the shape orcontour of the various sections. Other modiiications or variations inthe form may be made without materially departing from the spirit ofthis invention, and I therefore reserve the right to make such slightchanges as may suggest themselves and without departing from the spirito`i` this invention.

Having thus described the invention, what is claimed as new is- 1. Ajournal-bearing comprising sections adapted to interlock with eachother, for the full extent of corresponding' sides thereof, and a casinginclosing the sections, said sections being constructed on their innerfaces to form an opening for the reception of a journal.

2. A journal-bearing comprising sections having alternating ribs andgrooves for the full extent of corresponding sides thereof, the ribs onone section being disposed opposite and movable in the grooves or' theother section, a casing inclosing the sections, and adjusting devicesfor one of the sections working through apart 0f said casing.

In testimony whereof I aliix my signature in presence of two witnesses.`
